以原子精度调节纳米粒子(NP)组装的能力仍然缺乏,这阻碍了我们创建具有所需特性的分层NP组织。在这项工作中,一个层次的纤维(1D到3D)组装Au纳米粒子(21-金原子,Au 21)实现和进一步调制原子精度通过特定位点的定制的表面钩(由四个含苯基的配体与抗衡阴离子)。有趣的是,剪裁相关的计数器显着改变了两个数量级的NP组装固体的电输运性质,由于改变了配置的相互作用的π-π对的表面钩。总的来说,我们在原子级调制的层次NP组装的成功直接证明了NP配体和相关的抗衡离子如何能够以微妙的方式引导NP的1D,2D和3D层次自组装。这项工作扩展了纳米化学家的技能,合理规划的层次NP组装与可控的结构和性能。构建具有原子精度的纳米粒子组装体仍然是纳米科学的主要挑战。在这里,作者通过调节特定位点的表面配体和相关的抗衡离子,实现了对Au纳米颗粒的1D,2D和分级3D组装的原子水平控制。
The ability to modulate nanoparticle (NP) assemblies with atomic precision is still lacking, which hinders us from creating hierarchical NP organizations with desired properties. In this work, a hierarchical fibrous (1D to 3D) assembly of Au NPs (21-gold atom, Au21) is realized and further modulated with atomic precision via site-specific tailoring of the surface hook (composed of four phenyl-containing ligands with a counteranion). Interestingly, tailoring of the associated counterion significantly changes the electrical transport properties of the NP-assembled solids by two orders of magnitude due to the altered configuration of the interacting π–π pairs of the surface hooks. Overall, our success in atomic-level modulation of the hierarchical NP assembly directly evidences how the NP ligands and associated counterions can function to guide the 1D, 2D, and 3D hierarchical self-assembly of NPs in a delicate manner. This work expands nanochemists’ skills in rationally programming the hierarchical NP assemblies with controllable structures and properties. Constructing nanoparticle assemblies with atomic precision remains a major challenge in nanoscience. Here, the authors realize atomic‐level control over the 1D, 2D and hierarchical 3D assembly of Au nanoparticles by modulating the site‐specific surface ligands and associated counterions.
